They were the first Europeans to cross the northern Great Plains and reach the mountains. (See Verendrye Brothers" journey to the Rocky Mountains for details of the expedition) Francois then returned east and served in the army during the Seven Years" War. He died on July 31, 1794 in Montreal.
He was one of two brothers to use the title "Chevalier" the other being Louis-Joseph.

With his death, the name Louisiana Vérendrye disappeared.
